Dear Mr. Goodrich:
In accordance with your application received June 24, 1996 we are forwarding herewith Permit
No. WQ0002284, dated October 17, 1996 to the Kinnakeet Shores Partnership for the construction and
operation of the subject wastewater rotary distribution facilities. The request for suspension of the
groundwater monitoring requirements, until the permitted capacity of the wastewater treatment facility has
been reached, has not been approved by the Division's Groundwater Section, however, the monitoring
requirements have been modified. The request was not approved based on the fact that the Groundwater
Section's 2L standards have been violated occasionally. The monitoring requirements have been modified
to require monitoring for fecal coliform instead of total coliform.
This permit shall be effective from the date of issuance until September 30, 2001 shall void Permit
No. WQ0002284 issued January 23, 1992 and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements in this permit. Failure to
establish an adequate system for collecting and maintaining the required operational information will result
in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer
27447, Raleigh, NC 27611-7447. Unless such demands are made this permit shall be final and binding.
If you need additional information concerning this matter, please contact Rick Moore at (919) 733-
5083 extension 527.

specifications, and other supporting materials. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.

2. The Washington Regional Office, telephone number [phone] shall be notified at
least forty-eight (48) hours in advance of operation of the installed facilities so that an in -
place inspection can be made. Such notification to the regional supervisor shall be made
during the normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday,
excluding State Holidays.
3. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective actions, including those
actions that may be required by this Division, such as the construction of additional or
replacement wastewater treatment or disposal facilities.
4. This permit shall become voidable if the soils fail to adequately assimilate the wastes and
may be rescinded unless the facilities are installed, maintained, and operated in a manner
which will protect the assigned water quality standards of the surface waters and ground
waters. The ponding of wastewater on the surface of the distribution field when the dosing
cycle commences shall be considered as evidence of failure of the soils to adequately
assimilate the wastewater. Additionally, such failure shall be interpreted as a violation of
this permit condition.
5. The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Water Quality.
6. Adequate measures shall be taken to divert stormwater from the high rate infiltration area
and to prevent wastewater runoff.
7. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
8. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
9. The following buffers shall be maintained:
a) 400 feet between high rate infiltration unit and any habitable residence or place of public
assembly under separate ownership or which is to be sold,
b) 200 feet between high rate infiltration unit and any private or public water supply
source and any streams classified as WS or B,
c) 200 feet from mean high water between high rate infiltration unit and any "SA" or "SB"
classified surface waters,
d) 200 feet from normal high water between high rate infiltration unit and any other
stream, canal, marsh, or coastal waters,

surface water diversions, etc.) and from any groundwater lowering and surface
drainage ditches,
2

h) 100 feet between high rate infiltration unit and property lines,
i) 50 feet between treatment units and property lines, and
j) 50 feet between high rate infiltration unit and other treatment units and public right of
ways.
Some of the buffers specified above may not have been included in previous permits for
this waste treatment and disposal system. These buffers are not intended to prohibit or
prevent modifications, which are required by the Division, to improve performance of the
existing treatment facility. These buffers do, however, apply to modifications of the
treatment and disposal facilities which are for the purpose of increasing the flow that is
tributary to the facility. These buffers do apply to any expansion or modification of the
high rate infiltration areas and apply in instances in which the sale of property would cause
any of the buffers now complied with, for the treatment and disposal facilities, to be
violated. The applicant is advised that any modifications to the existing facilities will
require a permit modification.
10. A usable green area shall be maintained for wastewater disposal. The green area shall have
the capability of accommodating the average daily flow of the facility being served without
exceeding the loading rates of the green area. A "green area", as defined in 15A NCAC 2H
